• Environmental compliance assurance meeting RoHS 3 and REACH regulations for safe use in regulated industries

Professional Applications & Engineering Value

This precision shoulder screw addresses critical alignment and vibration challenges in industrial machinery, automation systems, and precision instruments. The 18-8 stainless steel construction combined with passivated finish provides exceptional corrosion resistance, making it ideal for harsh manufacturing environments where chemical exposure or moisture is present. The integrated nylon patch thread locking technology prevents loosening under continuous vibration, eliminating the need for additional locking hardware and reducing assembly time. The precisely controlled 6mm shoulder diameter with tight tolerance ensures accurate component positioning in rotating assemblies, bearings, and linkage systems, while the hex socket drive allows for high-torque installation in confined spaces. These engineering features combine to deliver reliable performance in precision mechanical assemblies where alignment accuracy and vibration resistance are critical to operational success.
